Operating instructions
Note
h Have
your expert technician explain the operation of the VR 81 remote control unit once the installation is complete. This will prevent involuntary changes to the settings.
Note
Also read the operating manual for the VRC 430
controller. This describes how important
parameters of your heating system
can be adjusted (e.g. time window). An
explanation of technical terms and important
functions is provided in alphabetical order at the
end of this document.

Appliance features
The VR 81 remote control unit is a wired remote control
unit for a heating circuit and is used in combination with
the VRC 430 controller. Communication with the boiler is
achieved via a 2-lead bus line (eBUS).
You can adjust or modify the main functions via the VR 81
remote control unit (operating mode, target room
temperature).
Only one VR 81 remote control unit can be used.
